Background: Renal ischemia reperfusion injury may occur in a variety of clinical situations, following a transient drop in total or regional blood flow to the kidney. This study was performed to investigate the protective effects of different antioxidants such as vitamin C, vitamin E, hydrocortisone and combination of these agents against experimental renal ischemia-reperfusion injury....

Introduction: The aim of this study was to investigate the effect of angiotensin II (Ang II) and losartan injections into paraventricular nucleus (PVN) on renal ischemia-reperfusion injury. Methods: After right nephrectomy in male rats, a cannula was inserted into the right PVN. One week later, renal ischemia-reperfusion (IR) injury was induced by clamping the left renal artery for 45 min, a...

Objective(s): We investigated the role of nitric oxide (NO) in the protective effects of remote ischemic per-conditioning (rIPerC) on renal ischemia/reperfusion (I/R) injury in male rats. Materials and Methods: I/R treatment consisted of 45 min bilateral renal artery ischemia and 24 hr reperfusion interval. rIPerC was performed using four cycles of 2 min occlusions of the left femoral artery an...

objective(s):acute kidney injury (aki), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  renal ischemia-reperfusion, one of the main causes of aki, is of particular importance in the setting of kidney transplantation. materials and methods: sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

Renal ischemia–reperfusion (IR) is inevitable in partial nephrectomy and kidney transplantation. Acute tubular necrosis (ATN) induced by renal IR causes the loss of functional units kidney, pathologically presenting as nonhomogeneous distribution normal uriniferous tubules usually used to characterize activity. Optical coherence tomography (OCT) has been proven have ability image microstructure...

Time course of renal ischemia/reperfusion and distance organ; lung dysfunction in male female rats

Background: Previous studies have shown increases in endothelin (ET) concentration of plasma and renal tissues in acute renal failure (ARF).  ET has a potent vasoconstrictor effect, through binding with its ETA receptors, and may play some roles in renal hemodynamic dysfunction in ARF.Objective: To examine the beneficial effect of a selective ETA-receptor antagonist on renal dysfunction and tis...

background renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered principal components involved in the pathophysiological tissue alterations observed during renal ir. objective in this study, we compared the effects of melatonin (mel) and erythropoietin (epo), which are known antioxidant and anti-inflammatory agents, in i...

objectives: curcumin has anti-inflammatory and antioxidative properties. the objective of this study was to investigate the therapeutic effects of curcumin on functional disturbances, oxidative stress, and leukocyte infiltration induced by renal ischemia/reperfusion (i/r). materials and methods: animals were randomly divided into 9 groups. the groups with 24-h reperfusion consisted of sham-24h,...

introduction: this study was designed to evaluate the effects of treatment with flaxseed oil (fso) on renal ischemia-reperfusion (rir) injuries in rats. materials and methods: in this study, 32 wistar rats were randomly studied in four groups: co+ns (control group with normal saline administration), sh+ns (sham group with normal saline administration), rir+ns and rir+fso. fso (0.2 ml) was admin...
